Abstract
The development of approaches to the creation of new materials with functional properties is one of the main directions for progress of their application in various fields. This work proposes an approach to surface modification of polyamide-12 (PA) powder with single-walled carbon nanotubes (SWCNTs) to impart electrical conductivity and create a material suitable for selective laser sintering (SLS) 3D printing. A previously unknown transition in the conductivity character change with increasing SWCNTs content on the surface of polymer powder particles, demonstrating a change in the state of the electrically conductive network from quasi-planar to spatial, was discovered. The main parameters of the resulting powders were also studied, which determine the possibility of their use for the SLS method: flowability, compactability, transmittance and morphology. As a result, a simple method of new materials obtaining based on PA/SWCNTs with high electrical conductivity was proposed, which are suitable for application in 3D printing.
期刊介绍：
Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
